V The oscillatory arm 1s formed Wlth a boss 17 at its lower end which boss is apertured to accommodate the shaft 13 .serving as a suitable support for arm 17.- The means o comprises a gear 20 ?ixedly mounted on the shaft 18 at one. side ofthe arm 17, and an intermeshing gear 21 fixedly mounted 'at its hub 21a on the shaft 13 and between the bearings l14 thereof, and in the plane of rotation of the gear 20. The means of operative connection cl comprises a pinion 22 ixedly mounted on the shaft 23 of an electric motor 24 on the base 16, and a gear 25 fixedly mounted onfthe shaft 13 beside the gear 21 and in mesh withl such pinion. The motor 24 constit'utes the motive means D and the supply of| electrical energy to such motor may be controlled through a switch 26 in the circuit wires 27 and 28.

A plurality of drive pulleys 29 and 30 are secured to the shaft 18, one at-each side of 'the arm 17 and the grooves 29a', and30a' Iprovidedin the respective pulleys 29 and 30 are each in a plane of one ofthe sets of pulleys 12 and the'plane of belt actuation', the belts being indicated at 29b'and 30" re-- i .leys 12; While the belt 3()b is rove about the.

drum and fixed to a frame member at "one of its ends as at 50 and secured gto'brake operating means g at its other end." ThefI brake operating means g may comprise a conveniently located pedal '51, pivotal-ly mounted on the base 16 as at 52andhaving an upstanding bell-crank arm 53, and a' brake operating rod or link 54 p'ivotally secured at one end to the belt crank arm 53,

as at 55, and pivotally secured to one' end of the brake band, as at 56. .The rgd- 54' passes through a boss 57 provided on the framework or the upright 15 thereof and extending into the path of the rod, a' compressionspring 58 being interposed between such boss and the end of the brake band at the pointof pivotal connection 56.

The means F for rotating the tire `shown in dotted lines at F', may comprise a pluh rality of radially disposed conical rollers 59 provided with shafts-60 disposed obliquely to the horizontal plane and mounted in Journal boxes 61 provided beneath'a' tabletop 62 upon which the tire may be placed. The table top isjcut away as at 62 to' permit the intrusion of the rollers therethrough forcontact with the tire F. The means G is shown as comprising 'a plurality of obliquely disosed shafts 63, one vof which is provided or actuating each of the rollers 59, a1 horizontally disposed miter gear 64 fixed to 'a shaft 65, a worm wheelV 66 likewise fixedto the shaft 65, a worm 67 fixed to a shaft 68 suitably jou'rnaled on the base 16, as at 68, a sprocket 69 on the Worm shaft 68, a chain 70 rove about' the sprocket 69 and about a smaller sprocket' 71 fixedly mounted yon the countershaft 13,

and gearing provided on the shafts 63 and on the shafts 60 of the 'conical rollers 59, one of thel shafts 63 being arranged to transmit litV powerfrom the miter gear 64 `to each of the conical rollers 59 by means of the the shaft 63 which comprise in eac a lower initer gear 72 and an upprmiter gear 73,the lower miter'gear 72 meshing with the'm'iter gear 64 and the upper: miter' gearing on `Instance,

The shaft 65 is journaled in thefrarnework or base of the ,i mechanism as atfv' and the worin 67 provided on the shaft 68 actuates the gear 6i through the worm wheel 661 fixed to 'the' shaft. yl .j r Y The operation, method of' use and advantages ofthe invention will "be readilyunderf stoodl 'froi'i'il tlie fore Ging description taken e gategoffgthe 'shuttle bemg remoyed) insiland the following statement:

Figl 1, a cirular tire to be `wrapped Imay be placed on the table top 62 and on theconical rollers 59 for rotation thereby. After'the tire has Vbeen so `positioned the shuttle may be-a ain completed byreplacing'. the gate and olting or otherwise securing the same in place, and the tape from the spool 7 starb ed about the tire. Upon throwing the electric switch 26 the motor will be energized `ubid will drive the countershaft ,13 through the means of o erative connection d, and

neet-ion he shuttle will thus be set in motion by the power imparted by the belts 29b and 30h, and will, in its rotation, carry the spool v'i' around the portion of the tire in the wrapping zone for. the planeof shuttle A rotation, and as, due to the inter-connection of the rollers 159 with the-eountershaft 13 and throu h the saine with `the motive means D, the rol ers will be set in motion upon the tirewill be rotated about its axis to present new surfaces or portions to be wrapped in the wrapping zone. The nature of the intermediate gearing provided between lthe :countershaft and the rollers permits of a 1 at speed reduction as between the couni tershaft. 13 and the rollers'59 so that such 45 rollers are moved at just the proper rate to 4 wrapping zone in the shuttle as the opera-` tion roceeds.
